TECHNICAL FIELD

This invention relates generally to olefin metathesis catalysts comprising aniline type ligands, to the preparation of such catalysts, compositions comprising such catalysts, methods of using such catalysts, and the use of such catalysts in the metathesis of olefins. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and in industrial applications such as oil and gas, fine chemicals and pharmaceuticals.

BACKGROUND

Since its discovery in the 1950s, olefin metathesis has emerged as a valuable synthetic method for the formation of carbon-carbon double bonds. Recent advances in applications to organic syntheses and polymer syntheses mostly rely on developments of well-defined olefin metathesis catalysts.

The technology of ruthenium metathesis catalysts has enabled the development of several research platforms including: ring opening metathesis polymerization (ROMP), ring opening cross metathesis (ROCM), cross metathesis (CM), ring closing metathesis (RCM).

The incorporation of N-Heterocyclic Carbene (NHC) ligands or of cyclic alkyl amino carbene (CAAC) ligands, has played an essential role in the development of ruthenium metathesis catalysts. Metathesis catalysts, based on ruthenium, are known and have been studied.

However, there is an ongoing need for olefin metathesis catalysts, particularly ruthenium metathesis catalysts with improved characteristics which will further enable their use in a wider array of applications and olefin metathesis reactions, and for methods to prepare them.

In one embodiment, the invention provides an olefin metathesis catalyst wherein the Moiety (DIII) is represented by:

The present invention concerns also processes for preparing the olefin metathesis catalysts described herein. The olefin metathesis catalysts according to the invention can be prepared analogously to conventional methods as understood by the person skilled in the art of synthetic organic chemistry.

The following synthetic schemes illustrate how the olefin metathesis catalysts of the invention can be generally synthesized.

Generally, the reactions take place at room temperature. The ratio between the acetonitrile catalyst and Moiety (D), aniline type ligand, is 1:1 mol. The reaction mixture is stirred for 30 minutes, diluted with hexanes, and a microcrystalline precipitate is formed. The solid is filtrated, washed with hexanes and dried in vacuum to afford the new olefin metathesis catalysts.

At this stage, those skilled in the art will appreciate that many additional compounds that fall under the scope of the invention can be prepared by performing various common chemical reactions.

For example, the olefin metathesis catalysts are typically added to a resin composition as a solid, a solution, or as a suspension. When the olefin metathesis catalysts are added to a resin composition as a suspension, the olefin metathesis catalysts are suspended in a dispersing carrier such as mineral oil, paraffin oil, soybean oil, tri-iso-propyl-benzene, or any hydrophobic liquid which has an appropriately high viscosity so as to permit effective dispersion of the catalyst(s), and which is inert and which has a sufficiently high boiling point so that is does not act as a low-boiling impurity in the olefin metathesis reaction.

Olefins

Resin compositions that may be formed, comprise one or more cyclic olefins, besides the olefin metathesis catalysts of the invention. The cyclic olefin may generally be any strained or unstrained cyclic olefin, provided the cyclic olefin is able to participate in a ROMP reaction either individually or as part of a ROMP cyclic olefin composition. Such cyclic olefins may be optionally substituted, optionally heteroatom-containing, mono-unsaturated, di-unsaturated, or poly-unsaturated C₅ to C₂₄ hydrocarbons that may be mono-, di-, or poly-cyclic.

EXPERIMENTAL General Information—Materials and Methods

In the following examples, efforts have been made to ensure accuracy with respect to numbers used (e.g., amounts, temperature, etc.) but some experimental error and deviation should be accounted for. The examples are to be considered as not being limiting of the invention described herein.

All reactions involving metal complexes were conducted in oven-dried glassware under an argon or nitrogen atmosphere using standard Schlenk techniques. Chemicals and solvents were obtained from Sigma-Aldrich, Strem, Alfa Aesar, Nexeo, Brenntag, AG Layne and TCI. Commercially available reagents were used as received unless otherwise noted. Silica gel was purchased from Fisher (0.040-0.063 μm, EMD Millipore).

Catalysts C710 (M34) was prepared using known methods as described in WO2018/034931 A1.

¹H NMR spectra were recorded on a Varian 400 MHz spectrometer. Chemical shifts are reported in ppm downfield from Me₄Si by using the residual solvent peak as an internal standard (CD₂Cl₂ δ 5.32 ppm). Spectra were analyzed and processed using MestReNova software.

The GC analyses were run using a flame ionization detector. The Column used is: HP-5 from J&W, 30 m-0.25 mm i.d.-0.25 μm film thickness. GC method conditions: injection temperature, 250° C.; detector temperature, 280° C.; oven temperature, starting temperature, 100° C.; hold time, 1 min. The ramp rate was 10° C./min to 250° C., hold time 12 min; carrier gas helium.

The following abbreviations are used in the examples:

Ring Closing Metathesis of Diethyl Diallylmalonate

C853, C777, and C813 were benchmarked against the ring closing metathesis of diethyl diallylmalonate and compared to the standard C627. The progress of these reactions was followed by GC. Reactions catalyzed by C853 and C777 both afforded complete conversion to diethyl cyclopent-3-ene-1,1-dicarboxylate in less than 15 minutes whereas reactions catalyzed by C813 or M72 (C627) required approximately 30 minutes, as seen in FIG. 3.
